HUB-ATTACHING DEVICE.

SPECIFICATION forming part of Letters Patent No. 622,878, dated April 11, 1899.

. Application led Tune 18, 1898. Serial No. 683,789. (No model.)

To all whom, it may concern,.- tion 6, which slides in cont-act with a guide 7 Be it known that I, ALFRED W. ANTHOINE, upon the plate 5. The guide 7 is L-shaped,

a citizen ofthe United States, residing at having an upward extension S, which serves Lewiston, in the county of Androscoggin and to support the jaw F when it is closed upon 55 5 State of Maine, have invented certain new a nut. Upon the opposite side of each jaw is and useful Improvements in Vehicle-Hub a short straight side 9, which slides within Wrenches, of which the following is a specithe right-angled side 6 of the opposing jaw,

Each jaw there- The object of the present invention is to fore is guided between'the guides 7 S on one 6o Io produce a simple and effective hub-wrench side and the right-angled portion of the opfor vehicle-wheels. posing jaw on the other, the two jaws, taken The invention consists in various details of as a whole, being guided between the pair of construction and arrangement, which will be guides 7 8, which are rigidly supported on the pointed out in the following specication, refplate 5. 65 I 5 erence being had to the accompanying draw- The outer faces of the jaws have iianges l0, ings, in whichwhich confine the ends of spiral springs 11,

Figure 1 is an inner face view of a device said springs being interposed between the embodying the invention, partly in cross-secjaws and fixed abut-ments 12 and having a tion, a part being removed and the wrench tendency to close the jaws. The abutments 7o zo being Vshown open. Fig. 2 is an, inner face 12 are supported on the plate 5 and are forked view showing the wrench closed. Fig. 3 is a at their ends to receive the ends of the springs, l section on the line 3 3 of Fig. 1. Fig. 4 is a as shown in Figs. 2 and 5. The abutments perspective view of one of the jaws; and Fig. and guides are preferably formed integral 5 is a side view of` a jaw, showing the co'perwith the plate 5. Within each jaw, between 75 25 ating guides and spring. the guide portions 6 and 7, is a web 13, having Referring to the drawings, A indicates a a cam H, which has a larger recess 14, a hub; B, the box withinthe hub; C, the spinsmaller recess 15, and an intermediate curved die on which the wheel turns; D, the outer surface, the function of which cam will be band of the hub, and E the usual nut for represently described. The jaws are held in So 3o taining the hub on the spindle. Contact with the plate 5 by an oval ring 16,

My invention consists in a device whereby which lies within the jaws and is connected the hub may be connected with the nutE and to a hand-operated nut 17 on the outside of thenutremoved and replaced bysimply turnthe plate 5. The nut 17 has a shank 1S, ing the wheel, the device being made a perwhich extends through the plate 5 and is rig- 85 35 marient attachment ot' the hub, so that no idly connected to a socket 19, and the socket wrench need be carried in the vehicle. 19 is connected with the ring 16 at opposite The hub-wrench comprises a ring 1, which ends by short rods or pins 20. (Best shown in is attached to the band Dand forms to all ap- Figs. 1 and The rods 2O operate on the pearances a continuation ot' the band. As cams H, as will be presently explained. 9o

4o shown, the ring 1 is attached to the band by For convenience 4of construction the ring screws 2, which connect inwardly-projecting 16, the socket 18, and the rods 20 are cast in flanges 3 upon the ring with an inwardly-proone piece. In assembling the parts the shank jecting flange 4 upon the band. Any other of the nut 17 is inserted in an openingin the suitable means of connecting the ring and socket 19 and permanent-ly secured therein 95 45 band may be used. Upon the ring 1 is a plate by swaging lthe end of the shank or in any 5, which carries the working parts of the inother suitable manner. Forconvenience also vention. Apairof jaws F are supported upon the guides 7 8 and the abutments 12 are cast the plate and movable toward and from each in one piece with the plate 5. The joint be- Yother to grip and release the nut E, as will be tween the ring 1 and the band D and also roo 5o presently explained. i As shown in the drawthe joints between the nut 17 and the plate 5 ings, each jaw F has a right-angled side porand between the plate 5 and the ring 1 are suitably packed to keep out dust and prevent the evaporation of the oil from the spindle. i.

The operation of the invention is as f ollows: Normally the jaws of the clamp are pressed apart, as shown in Fig. 1, the rods 2O being located in the recesses 15 of the cams. The jaws are locked in this position because of the tendency of the rods 15 to stay in the recesses on account of the nature of the curve between the recesses 14 and'l. In this position the jaws are so far apart that they are free from the nut E, and as the wheel revolves the jaws revolve about vthe nut E, which remains stationary. When it is desired to remove the nut E, the hand-nut 17 is turned so as to bring the rods 2O into the larger recesses 14 of the cams. These recesses permit the rods 2O to turn into the position shown in Fig. 2. Simultaneously the jaws are closed -upon the nut E by the springs 11. Upon turning the wheel backward the nutE can now be unscrewed and the wheel removed from the spindle. The twisting strain imposed upon the jaws of the clamp in unscrewing the nut is sustained bythe stationary guides 7 and 8,

`the jaws being L-shaped and having their side portions resting upon said guides. The jaws are securely held in place by the springs 11 and the elliptical ring 1b'. When the wheel is removed, the nut remains clamped within the jaws of the wrench, and upon replacing the wheel and turning it forward the nut is again screwed onto the spindle. After Ithe nutis screwed into place the hand-nut 17 is turned to spread the jaws into position shown in Fig. 1, thus leaving the wheel free to turn in either direction without affecting the nutE.

Having described my invention, what I claim, and desire to secure by Letters Patent,

1. The combination withl the hub of Va vehicle, of a hub-wrench permanently connected thereto and comprising a transverse plate, a pair of guides vliked upon the plate, opposing jaws sliding in said guides, springs tending to press the jaws inward, cams upon said jaws and means operated by a hand-nut for spreading the jaws, substantially as described.

2. In a hub-wrench, the combination with a spindle and spindle-nut, of a hub turning on the spindle, a transverse plate secured to the hub, L-shaped guides on said plate, clamping-jaws sliding in said guides and adapted to grip the spindle-nut when closed and revolve freely about the spindle-nut when open, springs tending to press said jaws inward, cams and a pair of coperatin g pins for spreading the jaws and locking them in the spread position, and means for turning said pins to open and close the jaws, substantially as de scribed.

3. .In a hub-wrench, the combination with the fixed L-shaped guides of the opposing wrench-jaws, each jaw having a longer side adjacent to one of the fixed guides and a shorter side which is guided in the longer side of the opposing jaw, a web at the base of each jaw provided with a cam-surface, means for operating upon the cams to separate the jaws, and springs pressing on the backs of the jaws, substantially as described.

4. In a hub-wrench, the combination with the opposing jaws having the webs at their ,bases and the cam-openings in the webs ofthe rings 16 overlying the webs, the pins 2O connected with the ring and coperai'ing with the cams, and means for turning the ring and pins to separate the jaws, substantially as described.

5. In a hubwrench, the combination with the plate 5, of thexed guides, the opposing -jaws sliding in the guides,^the webs at the bases of the jaws and provided with cam-sun faces, thering overlying said Webs, the pins connected with the ring and cooperating with the cams, the socket to which said pins are connected and the hand-nut 17 upon the outside of the plate, said hand-nut being securely connected with said socket, substantially as described.

In testimony whereof I affix' my signature in presence of witnesses.

ALFRED W. ANTHOINE.
